We show that coherence induced by Fano interference can
enhance the power produced by photovoltaic devices, e.g. photodetectors and solar cells, as compared to the same
system with no coherence. No additional external energy
source is necessary to create such induced coherence. In
the present model, coherence generated by photocurrent increases
(for optically thin cells) the flow of electrons through
the load, which reduces radiative recombination and enhances
cell power. We discuss two schemes in which coherence
is generated between upper or lower energy levels. We
also study the influence of decoherence, τa, on cell power and
show that one can design a device with Fano enhancement
even at relatively large decoherence rates. Finally we investigate
the effect of ambient temperature Ta on the cell power
in a scheme with no interference and show that for certain
parameters power can be increased by increasing Ta.

The Agarwal-Fano process ofthe present paper, is modeling a quantum dot solarcell placed in a hohlraum which is driven by narrowband isotropic radiation. However, one can extend thepresent analysis to the case of directional incidentsolar radiation and isotropic spontaneous emission.
